        Lynis - System and security auditing tool


       lynis [scan mode] [other options]


       Lynis  is  a security auditing tool for Linux, macOS, and other systems based on UNIX. The
       tool checks the system and the software configuration, to see if there  is  any  room  for
       improvement  the  security  defenses.  All  details are stored in a log file. Findings and
       other discovered data is stored in a report file.  This can be used to compare differences
       between  audits. Lynis can run interactively or as a cronjob. Root permissions (e.g. sudo)
       are not required, however provide more details during the audit.

       The following system areas may be checked:

              - Boot loader files

              - Configuration files

              - Software packages

              - Directories and files related to logging and auditing


       When running Lynis for the first time, run: lynis audit system


       audit <type>
              Perform an audit of the selected type

              Upload the available report data file

              See HELPERS section for more commands.


       audit system
              Performs a system audit, which is the most common audit.

       audit system remote <host>
              Provide commands to do a remote scan.

       For more scan modes, see the helper utilities.


       --auditor <name>
              Define the name of the auditor/pentester. When a full  name  is  used,  add  double
              quotes, like "Your Name".

              Perform automatic scan with cron safe options (no colors, no questions, no breaks).

              Display debug information to screen for troubleshooting purposes.

              Display detailed information useful for developers when creating tests.

              Perform the audit on a running or mounted system (see --rootdir)

       --help Show available commands and most-used options.

       --logfile </path/to/logfile>
              Defines location and name of log file, instead of default /var/log/lynis.log.

       --man  Show the man page. Useful for systems that do not have the man page installed.

              Disable colored output.

              Redirect all logging information to /dev/null, prevents sensitive information to be
              written to disk.

              Do not run any of the enabled plugins.

              Run a non-privileged scan, usually used for penetration testing. Some of the  tests
              will be skipped if they require root permissions.

       --plugin-dir </path/to/plugins>
              Define location where plugins can be found.

       --profile <file>
              Provide alternative profile to perform the scan.

       --quick (-Q)
              Do a quick scan (default: don't wait for user input).

       --quiet (-q)
              Run quietly and do not show anything to the screen. Will also enable quick mode.

       --report-file <file>
              Provide an alternative name for report file.

              Optimize screen output for light backgrounds.

       --tests TEST-IDs
              Only  run  the  specific  test(s). When using multiple tests, add quotes around the

       --tests-from-category <category>
              Tests are only performed if they belong to the defined category.  Use  the  command
               'show categories' to determine all valid options.

       --tests-from-group <group>
              Similar  to --tests-from-category. Only perform tests from a particular group.  Use
              'show groups' to determine valid options.

              Run from the current working directory.

              Upload data to Lynis Enterprise server (profile option: upload=yes).

              Show more details on screen, such as components that could not found. These details
              are hidden by default.

       --wait Wait  for  user  to  continue.  This  adds  a  break after each section (opposed of

              Run quietly, except show warnings.

              Multiple parameters are allowed, though some parameters can only be  used  together
              with  others. When running Lynis without any parameters, help will be shown and the
              program will exit.


       Lynis has special helpers to do certain tasks. This way the framework of  Lynis  is  used,
       while  at the same time storing most of the functionality in a separated file. This speeds
       up execution and keeps the code clean.

       audit  Run audit on the system or on other targets

       configure <parameter>
              Change or add settings to the config file

       generate <parameter>
              Generate specific details such as host IDs

       show <parameter>
              Show information, such as configuration and paths

       update <parameter>
              Perform activities regarding updating

       To use a helper, run 'lynis' followed by the helper name.


       Lynis uses exit codes to signal any invoking script. Currently  the  following  codes  are

       0      Program exited normally

       1      Fatal error

       64     An unknown parameter is used, or incomplete

       65     Incorrect data encountered
